A system thrashing is often a result of a sudden spike in page demand from a small number of running programs. Swap-token [3] is a lightweight and dynamic thrashing protection mechanism. The basic idea is to set a token in the system, which is randomly given to a process that has page faults when thrashing happens.

In computer science, resource starvation is a problem encountered in concurrent computing where a process is perpetually denied necessary resources to process its work. [1] Starvation may be caused by errors in a scheduling or mutual exclusion algorithm, but can also be caused by resource leaks , and can be intentionally caused via a denial-of ...
